Twenty Ten[resolved] Twenty ten: making images inline with each other (5 posts)

In a standard post, if you make the images small enough, they will run inline together. But if you add a caption, they refuse to run inline, no matter how small they're sized. Can someone tell me how to get around this? (PS: I'm a newbie, so be explicit with any advice!)

Thanks — Using Firebug, it looks as though any image that gets a caption is treated as its own <div, whereas if it doesn't have a caption it just shows up in the code as a link to the image. Any way to get around this? Any good plugins I should use for including multiple images in posts? I'd like to be able to create a line of thumbnails with captions.
